INKING ATTACHMENT FOR PRESSES.

Specification of Letters Patent.

Patented Jan. 2, 1917.

Application filed December 27, 1915. Serial No. 68,853.

To all whom it may concern Be it known that I, FREDERICK A. WIL- LIAMS, a citizen of the United States, residing at North Yakima, in the county of Yakima and State of WVashington, have invented certain new and useful Improvements in Inking Attachments for Presses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to improvements in inking attachments for presses, and has for an object to provide a device of this character which will insure a more even distribution of the ink from the fountain to the form rollers, and which can be regulated and adjusted to convey an increased supply of ink to any desired portion of said form rollers as it may become necessary, in order to print forms containing perpendicularly arranged heavy lines.

A further object of the present invention lies in providing an improved inking attachment for printing presses, which will broadly consist of a ductor roller mounted to swing between an-ink fountain and the press form rollers for transferring ink to the latter; said ductor roller being arranged to be operated automatically from the movable parts of the printing press, and being associated with mechanism under the con trol of the press throw-off for preventing the ductor roller from operatively' engaging the fountain when said throw-off is in the off position.

It is a further object of the present invention to provide, a device of the above character which will be constructed for ready attachment to any of the present forms of printing presses, and which will consist of few and simple parts readily assembled and connected for easy access for removal, repair and replacement.

The invention will be more particularly understood by reference to the accompanying drawings, in which the same parts are indicated by similar reference numerals throughout the several views, and in which Figure 1 is a fragmentary perspective view of a printing press equipped with an ink g t hm m .eonstrueted. in accordance with the present invention; Fig. 2 is a similar view taken from the opposite side of the printing press; Fig. 3 is a plan view of the spindle and ductor roller; Figs. 4: and 5 are perspective views of the bearings or castings; Fig. 6 is a detail view of the rod for operating the fountain distributing roller; Fig. 7 is a perspective view of the washer for operating the rod shown in Figa 6; Fig. 8 is a detail view of the rod for operating the ductor roller disengaging device; Fig. 9 is a perspective view of the washer for operating the rod shown in Fig. 8; and Fig. 10 is a detail view of the cam for operating the ductor roller spindle.

Referring more particularly to Figs. 12

of the accompanying drawings, 1 and 2 designate, respectively, the bed and oscillating platen of a Gordon or other printing press, the same being provided with form rollers 3 mounted on a swinging frame t to operate between the form on the bed 1 and an inking plate 5, which is rotated in the usual manner.

The parts of the press are operated in a well known manner, and the same is also equipped with the usual side arms indicated generally at 6, and with a throw-off device.

The frame of the press is provided with arms 7 and 8 which are preferably slotted to adjustably receive bolts for the connecting castings or bearings 9 and 10, illustrated more particularly in Figs. 1 and 5, and being provided with slotted extensions 11 and 12 for receiving the blocks 13 and 14c supporting the usual ink containing fountain 15. This fountain 15 is equipped with the usual device for regulating the flow of ink to a fountain roller 16, journaled in the blocks 13 and 1a, and having one trunnion 17 thereof extended to receive a ratchet wheel 18, with which cooperates a pawl 19 pivotally mounted on an arm 20, supported from a sleeve 21 mounted on the trunnion 17 between the block 14 and ratchet wheel 18.

The pawl 19 and associatedarm 20 are connected by a pin or other device 22, slidably engaging a rod 23, and mounted thereon between a pair of adjustable collars 24; and 25. The rod 23, as more particularly disclosed in Figs. 2 and 6, is connected at its lower end to an annulus 26 fitted over the washer 27, shown in Fig. 7, and which, as indicated in Fig. -2, is mounted on left- 32 for yieldably moving said spindle to shift hand roller frame at point where roller arm is connected to roller frame of the printing press.

It will be understood that as the washer 27 is rotated'by roller frame a reciprocating motion will be imparted to the rod 23 to escillate the arm 20 carrying thepawl19, which will therebybe actuated to engage the teeth of the ratchetwvheel 18 and intermit tently rotate the fountain roller 16.

The collars 24 and 25 are adjustable on rod 23 so as to bring the pawl 19 to a variety of positions with respect to the ratchet outer ends of the arms 29 and 30, said ductor roller being preferably of the size substantially as shown in the drawmgs, although the same mayv be of a length correspondlng to the length of the'fountain roller 16 and form rollers 3, when found desirable to supply an increased amount of ink.

Associated with the spindle 28 is a spring the ductor roller 31 to the position shown in Fig. 1, where the same is in contact with the fountain roller 16. At one end thereof the spindle 28 is provided with an arm 33 to which is secured a roller or other projection 34, arranged in the path of a cam 35 mounted to oscillate on a pivot 36 secured in the bearing 10.

The cam 35 is connected to be actuated by a rearwardly-disposed arm 37 from a rod 38, shown in Fig. 1 as beingconnected to the adjacent form roller side frame 4 as inclicated at 39.

It will be apparent that as the roller frames 4 oscillate to swing the form rollers 3 from the position shown in Fig. 1 to that shown in Fig. 2, the cam 35 will thereby be actuated to engage the projection 34 on the arm 33 and transmit a rocking movement to the spindle 28, which willshift the ductor roller'31 from engagement-with the fountain roller 16 into contact with the uppermost of the form rollers 3 (compare Figs. 1 and 2).

The spindle 28 at the end opposite the arm 33 is provided with an arm 40 for engagement by a pin 42, projecting from a sliding block 41 on a rod 43. An annulus 44 is connected to the lower end of the rod 43, and is fittedover a washer 45 (shown in Fig. 9) and which, as disclosed in Fig. 1, is mounted in connection'with the eccentric journal of the back shaft, which is operated in a well understood manner by the trip or throw-off of the press. I

to bring the ductor roller 31 into contact with the fountain roller16, when the throwolf mechanism of the press is in the off position. W'hen, however, during normal running of the press the washer 45 will be in position to maintain the rod 43 and associated parts in a lowered position so as not to interfere with the arm 40 when the spindle 28 is rocked upwardly to move the ductor roller 31 into engagement with the fountain roller 16.

7 It will be understood from the foregoing description, taken in connection with Figs. 1 and 2 of the drawings, that as the press is operated the ductor roller 31 is alternately oscillated between the fountain roller 16,

from which the same receives a supply of lnk, and the uppermost of the form rollers '3, to which the supply of ink is thereupon transferred. The ductor roller 31 may shifted longitudinally along the spindle 28 by the set screws or other means associated with the arms 29 and 30, accordingly as it is desired to convey an increased supply of ink to any particular portion of the form rollers to secure an eXtra heavy lining of the printed form. It is to be understood, however, that the ductor roller 31 need not necesssarily be of the size shown in the present drawings, as the character of the work may require that such roller be of substantially the same length as the fountain and form rollers.

It will be obvious that various modifications might be made in the herein described apparatus, and in the combination and arrangement of parts without departing from the spirit of this invention.

- Having thus particularly described my invention what I claim and desire to secure by Letters Patent of the United States is 1. The combination with a printing press having a movable form roller, of an inking attachment therefor including a fountain, a fountain roller associatedwith said fountain, a spindle-journaled to rock between said fountain and form rollers, arms adjustably to supply an increased amount of ink for heavy perpendicular lining of the form, and means for rocking said spindle to swing the ductor roller between the fountain and form rollers, substantially as described.

2. The combination with a printing press having a form roller, and a throw-ofi device, of an attachment therefor including an ink fountain, a ductor roller mounted to swing between said fountain and form roller, a spindle carrying said ductor roller, means for rocking said spindle, an arm on said spindle, a rod connected for operation to the throw-oil" device, and adjustable means on said rod for limiting the throw of said arm when the throw-off device is in 0H position to prevent engagement between said ductor roller and fountain, substantially as described.

3. The combination with a printing press having a form roller, and a throw-off device, of an attachment therefor including an ink fountain, a ductor roller mounted to swing between said ink fountain and form roller, a

spindle for carrying said ductor roller,

means for rocking said spindle, an arm on said spindle, a rod connected for operation to the throw-off device, a block slidable on said rod, means for adjusting said block on said rod, and a pin on said block for engaging said arm when the throw-off device is in off position to prevent engagement between said ductor roller and fountain, substantially as described.

i. The combination with a printing press having a form roller, a swinging carriage supporting said form roller, and a throw-off device, of an attachment for said press including an ink fountain, a fountain roller associated with said ink fountain, means for intermittently revolving said fountain roller, a rock spindle, arms adjustably Copies of this patent may be obtained for five cents each, by addressing the mounted on said rock spindle, a, ductor roller carried in said arms and adapted to swing between said fountain and form rollers, said ductor roller being of inferior length with respect to said fountain and form rollers and adjustable longitudinally of said spindle for bringing the same to any predetermined longitudinal portion of said fountain and form rollers, an arm on said spindle, a cam adapted to engage with said arm to rock said spindle, connections between said cam and the form roller carriage for automatically actuating the former, a second arm on said spindle, a rod connected for operation to the throw-off device, and means on said rod for limiting the throw of said arm when the throw-off device is in off position to prevent engagement between said ductor and fountain rollers, substantially as described.

5. The combination with a printing press having form rollers, and a throw-off device, of an attachment therefor comprising an ink fountain, a fountain roller associated with said ink fountain, means for intermit- 'tently revolving said fountain roller, a spindie, a ductor roller of lesser diameter than said form rollers adjustably mounted on said spindle to swing between the same and said fountain roller, a cam for rocking said spindle to operate the ductor roller, connec tions for operating said cam arranged between the latter and the movable parts of the press, an arm on said spindle, a rod connected for operation to the throw-off device,

and adjustable means on said rod for limit- I ing the throw of said arm when the throwofi' device is in off position to prevent engagement between said ductor and fountain rollers, substantially as described.
